BEN .P. JOHN SON F SPRINGFIELD, OHIO, ASS IGNOR T0 EDWARD E. GREINER OF SPRINGFIELD, OHIO V I DOUBLE RUN FORCE FEED GRAIN DIS'IFRIB' IJ'TOR Original application filed February 6, 1932, Serial No. 591,407. "Divided and this application me 7 February 6. 1932. Serial No. 591,409, I p

This invention relates to grain distributors, and the present application is a divi- S1011 of my copending application filed February 6,1932, Serial No. 591,407. The prin- 3 cipal object of the invention is to provide novel double-run adjustable throat forcefeed grain distributors for attachment to the feed hoppers of seeding machines or the like, said distributors having a single rota- 13 table feed wheel dividing the interior of the distributor into separate grain compartments, and each face of the Wheel. operating toindependently feed seed behind their individual furrows, whereby I accomplish with one distributor the same results by present practice accomplished with two, my single distributor feeding two furrows.

A further. object of 'the invention is to provide novel grain distributors of the above type with novel independently and simultaneously adjustable throats for regulating the amounts of seed fed to the respective furrows by each side face of the rotatable feed wheel, with means on the outer side of the casing for adjustingand maintaining the throats in adjusted positions.

A- still further object of the invention is to provide an indicator pointer and dial to insure accuracy in setting each independent- 3O ly adjustable throat to feed the same amount of feed, as distinguished from the present practice in which all the various distributors are regulated by means of a rod extending between the distributors andoperated by means of a lever at the end of the grain hopper, which method is costly to construct and mount, and does not insure an accurate adjustment for each distributor.

Other minor objects of the invention will be hereinafter set forth.

I will explain the invention with reference to the accompanying drawings which illustrate several practical embodiments thereof to enable others familiar with the art to adopt and use the same; and will summarize in the claims, the novel features of construction, and novel combinations of parts, for which protection is desired. I

'tributor preferably In said drawings Fig. 1 is a side elevation showing my distributor secured to the: bottom of a seed hopper,the hopper being shown in; section;

Fig. 2 is a frontelevationthereof, partly broken away.

Fig. 3. is a top plan view of the distributor,

detached. Fig. 4 is a front elevation of the distributor showing the means for simultaneously operating both adjustable throats with a single knob. Figs.-5 and 6 are fro tions respectively of theadjustable throat gate, detached. i v s Fig. 7 is a perspective view of the gate. As shownin the drawings,-my novel discomprise's a casing adapted to be mounted across an opening H, preferably 7 of general rectangular shape, in the bottom of the feed hopper H, said casing having'a flange 1 at:its upper end conforming with the curvature of the bottom of the hopper and with theshape of the opening H. Preferably the casing is made'in two complemental and symmetrical alves 2 and 3 bolted together on the centerline of the casing. In each half 2 and-3 of .the casing isa bearing 4 adapted toreceive a hub 5a. of the force feed wheel 5 disposed on the centerline of the casing and dividing the interior of the casing into two nt and. rear elevav separate seed compartments A and B, (Figs. I

2 and 3), th

e compartments being open at the'top, the

walls thereof conforming with they periphery of the feed wheel 5 and extending down the web of wheel 5 on one side of the hub bearing 4 and below and around the bearing 4 and partly up the wheel 5 at the other side of the bearing,.in the usual manner, to 6 (Fig. 1), the walls ofeach compartment gradually contracting towards the point of discharge 6 adjacent the lower'periphery'of the wheel 5, whereby grain falling from the hopper H into the seed compartments A and B on each side of the feed wheel '5 will be fedby the portion 'ofthe web of the wheel 5-in therespective compartments to the discharge points 6 of the compartments on each the point of discharge side of the wheel. The wheel 5 is preferably provided with a peripheral flange 5?) having teeth 50 1) formed on its inner face, at each side of the web, for assisting in forcibly feeding the seed through the compartments A and B as the wheel 5 is rotated in the direction shown by the arrow in Fig. 1 by the drive shaft S which passes through the hub 5a. The flange 5?) of the wheel 5 is preferably flush with the periphery of the casing sections 2 and 3 asshown and forms part of the outer wall of the casing, each section 2 and 3 being provided. with lugs 2a, 3a, which meet across the flange of the wheel 5, the lugs being held together by bolts 7 and properly spacing the casing sections 2 and 3 with respect to the wheel 5. In the outer wall of each seed compartment A and B. as shown in Figs. 1, 2 and 3, is an adjustable throat, comprising a gate 10 disposed in an openingtherefor, each gate 10 forming part of-the exterior wall of its compartment, and being hinged at its upper end to the side wall of the casing by means of a pin 11 passing through perforated lugs 10a on the gate and 12 on the casing as indicated in Figs. 1, 5 and 6; the gate curving inwardly and downwardly adapted to engage the web of wheel 5 adjacent its lower periphery, whereby as the gate is swung towards the web of the wheel 5, as in full lines in'Fig. 2, the throat of the seed compartments will be narrowed to restrict the amount of seed passing to the point of discharge 6, and whereby swung away from the web of wheel 5. as in dotted lines in Fig. 2, thethroat will be en-' larged to permit agreater amount of seed to pass to'the point of discharge 6. At the lower end of each gate 10. on its rear face, is a flange 100 making a close'fit within the sides of the opening in the wall of the easing, to prevent seed from escaping from the compartment around the sides of'the gatein any position of adjustment of the gate.

On the rear face of each gate is an outwardly projecting lug 10d having an elongated slot 106 (Fig. 2) adapted to receive an eccentric cam 13 mounted upon a shaft 14 journaled in perforated lugs 15 on the sides of the casing sections adjacent'the gate 10, said shaft 1 being rotatable by a knob 16 at the front of the casing whereby as the shaft 14 is rotated the gate 10 will be swung towards or away from the web of the wheel 5.

On the front face of the casing, as shown in Fig. 2, are indicating indicia 17 cooperating with the knobs 16 whereby the knobs 16 may be readily set to accuratelyfeed the required amount of seed from'the compartments at each side of the wheel 5, the seeds falling into a single throat B (Fig. 2) having a division plate C below the centerline of the wheel 5, to divide the throat B into as the gate is two compartments feeding seed from the respective compartments through branches D and E to their respective seed furrows. In Fig. 2 the gates 10 are shown as independently adjustable by the use of the separate knobs 16. j

In Fig. 4 a modification is shown in which a centrally disposed rotatable knob 18 is mounted on the front face of the casing cooperating with the setting indicia 18a, said knob 18 beingconnected by links 19 to eccentrics'14a on the shafts 14 controlling the separate gates 10, whereby a single setting oftheknob 18 will simultaneously operate both of the gates 10 and maintain the same relative opening or closing movements for each gate 10.
